- I did the same thing a while ago for Bourne Shell, basically because I
- use tcsh all the time on Unix systems, but the best Unix-style shell for
- DOS I've found is the Data Logic MS-DOS sh.
-
- As you can see, mine is a bit more compact than Gilbert's 8^)...
- It doesn't support the '+n' switch but it's just about as minimalist
- as you can get.
-
- Note that older Bourne Shells don't have shell functions.
-
- Share and enjoy.
